While many programs and initiatives have been implemented to address the prevalence of substance abuse among homeless youth in the United States, they don't always include data-driven insights about environmental and psychological factors that could contribute to an individual's likelihood of developing a substance use disorder. Now, an artificial intelligence (AI) algorithm could help predict susceptibility to substance use disorder among young homeless individuals, and suggest personalized rehabilitation programs for highly susceptible homeless youth.

Pregnant women from sub-Saharan Africa with malaria and human immunodeficiency virus (HIV) have a higher prevalence of anemia than pregnant women without infections, according to researchers. The findings may have implications for reducing the risk of death in pregnant women and preventing low birth weights and neurocognitive impairment in their children as a result of anemia.

Researchers have identified a set of modifiable factors from a field of over 100 that could represent valuable targets for preventing depression in adults. The team named social connection as the strongest protective factor for depression, and suggested that reducing sedentary activities such as TV watching and daytime napping could also help lower the risk of depression.

New research delineates how two relatively common variations in a gene called KIF3A are responsible for an impaired skin barrier that allows increased water loss from the skin, promoting the development of atopic dermatitis, commonly known as eczema. This finding could lead to genetic tests that empower parents and physicians to take steps to potentially protect vulnerable infants from developing atopic dermatitis and additional allergic diseases.

One-third of the people who could benefit from a special type of savings account to cushion the blow of their health plan deductible aren't doing so, a new study finds. And even among people who do open a health savings account, half haven't put any money into it in the past year. This means they may be missing a chance to avoid taxes on money they can use to pay for their health insurance deductible and other costs.

Researchers have gained new understanding of the virus that causes hepatitis B and the 'spiky ball' that encloses its genetic blueprint. They looked at how the capsid -- a protein shell that protects the blueprint and also drives the delivery of it to infect a host cell -- assembles itself. The capsid is an important target in developing drugs to treat hepatitis B, a life-threatening and incurable infection that afflicts more than 250 million people worldwide.

To improve our understanding of the antibody response conferring protection against HBV infection, scientists have produced and characterized human monoclonal antibodies specific to viral envelope antigens, referred as HBsAg, from blood memory B cells isolated from HBV vaccinees and natural controllers.

Researchers have discovered which gut bacteria help our immune system battle cancerous tumors and how they do it. The discovery may provide a new understanding of why immunotherapy, a treatment for cancer that helps amplify immune response, works in some cases, but not others. The findings show combining immunotherapy with specific microbial therapy helps the immune system to recognize and attack cancer cells in three forms of cancer.
